Edge 830 surgery
A little over a year ago, the screen of the Edge 830 started 'delaminating'. A common issue with the x30 series afaik. It kept getting worse—starting as a small spot, but spreading more and more. Last winter I already bought a new screen and the recommended adhesive, but I kept postponing the job because everything still worked fine. However, since the doctor currently won't let me cycle, I finally grabbed the parts. And if it doesn't work out or if the screen turns out to be fake or something, I can buy a new one at my leisure.
The delamination is nothing more than the black coating on the back of the screen coming loose; the coating remains stuck to the glue/housing. Despite some rain during rides, the inside of the device stayed dry as far as I can tell.
The screen came off quite easily because it had already partially detached; I worked around it with a thin blade and sliced through the glue. Most of the glue was at the bottom, which was the hardest part. Then I disconnected the two connectors. Most of the work was removing the glue residue: repeatedly soaking it with some isopropanol and scraping it away. After that, I connected the new screen and briefly tested whether it worked—yes, including the touch functionality. Then I applied the glue (pain in the ass job), pressed the screen into the glue, and now it's clamping for a few hours (using the eraser to apply some extra pressure there). By the way, there is ridiculously little glue in those tubes; I needed 3 of them.
